COMBINED C'l'IRIiINZG AND lWAVING IRON.

iApplication filed. August 9, 1 924. serial No; 731;219.

To all who 1n iii may concern:

Be it known thatI, NATHAN D. 'TH MI soN,-Jr., a citizenof the'UnitedStates, residing in the city of St. Louis, State of Missouri, haveinvented a certain neW- and use- 'ful Improvement inwa Combined Curlingand W'Vaving Iron, or Which-the following is an exact, clear, and fullspecification.

My invention relates to combined hair curlers anchliairqwavers andspecifically to a mechanism for changing from one form to theother.

"The princ pal obyect of any invention is to provide *a-mech anism: forchanging from a curling rod-to a hair rv-aver, or vice versa,

that is positive' inaction, sturdy and rigid when combined and verydurable and dependable in use. I

Another ob ect of -my invention is the production of a combined haircurling rod and "hair waver that may be produced at a broken off. 7

' Fig, 5 is a cross section of 'Figul, at 5--5. da 'omen skilled an theart of personal adornment have learned that l a harmonious and artistici blending of Waves and: curls ci-an be 'Wrought'anto atypeof beauty andenchantment tha't cannoti besecured by. sim- PlG-WH-VQS-Ol' a cluster(if-curls; Therefore, there is a d'emand for a simple-andconvenientdevice that may be easily; and quickly transformed into eithera simple curling rod or 'a hair" waver.

Attempts to nieet thisreqirirement have not been entirely snccessfnl,beoause the mechanismdevised for -malnng the trans formation from asimple" heated curling rod to a hair waver has been either' t-oo frailand delicate, or has been :lackingimposit-ive action and durableanddependableiqualities.

To overcome these objections, I have devised a mechanism that ispositive in action,

sturdy, dependablfi and of great durability,

that may be manufactured at a very low cost and hence sold at areasonable price.

In Fig. 1, I"have'indicatedany prelferred method of construction of myinvention. v A'handle l is provided equipped with a ferrule 2,-l-1avinga' hollowbarrel 3, adapted to be heated-by an electricalheating element to which current is condncteduby wires-A, to which isattached a standard plug 5,

ada-liited to be scrmvedinto: any convenient z current carrying socket.

Ai -movable clamping jaw- 6 is in hinged relation at its inner end?wvitlr the heata'ble barrel 3. The hinge pin :8 is-positioned .at

some distance from the radial center totrthe barrel 3, so-that'when.t'hejaiv isiopenedito insert the barrel in the hair, thei inner end ofthe jaw (ileaves .thenbarrel aisutficient distance to permit theinsertingofnpractically the entire length of the barrel;

It is evidentthatit 'it be desiredto use any improved comh i-ned curlerand :Waver as a simple curlingarod, theinovablejaw-G must be bodilyremoved -With its Jh in'ged mechanism, so "tl-iat'the-iharrelfi presentsa plane smoo'th surfacecto'the hair. It,-.1s,

also apparent thatwwhen. the removable; aw 6 is in pla ce to'be used: asa :hairavaver, it musthave sullicientspring strength to clamp the 'hairfirm 1y, and since the spring imust yield to the strength of thethumb-often of a delicate Woman, it= isL-iin-portant that the downwandpressureoof the thumb cause dn ect verticalzlllOVGll'lt-llltz,Ofiitlle1111181 end of the aw 6,.and that alikeidirectlupward 1 vertical vmownnent of the ioppos'ite-ench of thejaw 6, Without neither longitudinal or torsional movement thereof. 1 I

To make certarnthe above aoutlinedgresuits ,1 have providedaJU-shapedhinge olip t 9, formed of sheet zinetal, so that the bottom ofthe U fits the barrel 3 closely and snugly,

thuslpreventing :lateralor torsional unovevment o'lithe upwardlyextending ears" 10 of ltheihinge clip 9, the-said 'sideears forming I weone-half: of the xhinge; the opposite half of the hingei being-formed-=by the straight downwardly turned embossed: sides-111 of the :heel orinner -end:=0f the movable jaW G.

Thus, sit -will: be seen 'th-atnny pressure ex- 2105 ertech .upon t-llelJoutton 12 canxonlynproduce a vertical mo.vement,1.or-" rotation: about-the hinge pin 8 in a vertical plane.

To further insure the positive and direct vertical action of the openingand closing 110 of the jaw, or clamp, 6 I have provided a relativelystrong, fiat spring 13, disposed. parallel to the longitudinal axis ofthe jaw 6, securely attached to the upwardly extended pressure arm 14,from where it extends forwardly and downwardly convoluting about thehinge pin 8. It is then extended diagonally upward and again bent in aneasy curve to give it pressure contact with the ferrule 52. The end 15is turned upwardly to facilitate attaching the clamping jaw 6.

The hinge clip 9 is provided with a rearwardly extending tail piece 16made integral with the hinge clip 9 and slightly depressed therefrom tofit the contour of the front end of the ferrule 52, and made curvilinearin cross section to conform to the curvature of a cross section of theferrule 2. Adjacent the end of the tail piece 16, an aperture 17 engagesa pin 18, radially projecting outwardly from the ferrule 2. The functionof the pin is to securely hold the hinge clip 9 in position againsteither longitudinal or torsional movement. The spring 13 has a two-foldfunction, in addition to holding the jaw 6 in parallel contact with thebarrel 3, it holds the tail piece 16 in firm contact with the ferrule 2.

By this method of construction it is seen that when the jaw 6 is inplace, it is as firmly held as if rigidly attached to the handle orbarrel and at the same time it may be quickly and easily attached anddetached.

WVhen it is desired to detach the movable clamping jaw 6 to convert thewaver into a simple curling rod, the combined curler and waver handle isfirmly held in the right hand with the clamping jaw downwardlypositioned in the palm of the left hand,

holding it firmly with the thumb and fingers. A slight downward pressureof the handle in the right hand causes the tail piece 16 to bedisengaged from the pin 17 when the handle is rearward, leaving theclamping jaw in the left hand. The reverse movements are necessary toput the clamping jaw in place.

.H-aving fully described my invention and the method of its operation,what I claim as new and useful and desire to secure, by Letters Patentis:

1. In a curling iron the combination of a heating rod and a clamping jawattachable and detachable thereto by means of a hinge clip encirclingthe lower half of said heating rod, said hinge clip having flat lugs, or

ears, projecting upwardly some distance above the top of said heatingrod, said ears having perforations therein adapted to engage oppositeends of a hi'ngepin laterally disposed above the said heating rod, 000

clamping jaw causes the said jaw to rotate in a vertical plane about thesaid hinge pin.

2. In a curling iron the combination of a heating rod with a clampingjaw pivotally attached thereto by means of a hinge clip encircling thelower half of said rod and having fiat, upwardly projecting ears, oneach side of said rod, parallel to the longitudinal axis of said heatingrod, spaced apart and perforated to engage a hinge pin in cooperationwith'similar perforated ears. depending from said clamping jaw andengaging the outer ends of said pin, said hinge clip having a rearwardlyextending tail piece, depressed a distance below the bottom of saidheating rod to conform to the contour of the front end of a ferruledhandle, said tail piece being perforated near its end to engage a pinradially projectingfrom aferrule upon the inner end of the handleof saidheating rod in such a manner that said perforation will disengage saidradially disposed pin when vertical pressure is applied to the inner endof said clamping jaw.

3. In a curling iron the combination of a heating rod with a clampingjaw semi-circular in cross section and adaptedto conform to the contourof said rod when longitudinally imposed thereon, said clamping jaw beingin hinged relation with said heating rod by means of a removable hingeclip into which said heating rod is inserted, said hinge clipco-operating with a flat spring having one end rigidly aflixed to theinner end of said clamping jaw from which said spring depends 1n aforwardly direction to a hinged pin about which it is convoluted in sucha manner that the bottom of the said convoluted portion contact with theupper surface of the said heating rod, thereby yieldably holding saidhe'ating rod between said spring and said hingeclip, said spring havingits opposite end reverse curved or S-shaped so that the end therebyreadily engages and yieldably clamps the ferrule upon the handle of saidheating rod between said flat curved spring and the tail piece of saidhinge clip.

In witness whereof I have hereunto aflixed my signature this 4th day ofAugust, 1924, in the presence of two witnesses.
